Amorphous calcium carbonate: Amorphous calcium carbonate (ACC) is the amorphous and least stable polymorph of calcium carbonate. ACC is monohydrate and is so unstable under normal conditions that aside from several specialized organisms it is not found naturally.Natron: Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na2CO3·10H2O, a kind of soda ash) and about 17% sodium bicarbonate (also called baking soda, NaHCO3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities.Pinna carneaCalcium deficiency (plant disorder): Calcium (Ca) deficiency is a plant disorder that can be caused by insufficient calcium in the growing medium, but is more frequently a product of low transpiration of the whole plant or more commonly the affected tissue. Plants are susceptible to such localized calcium deficiencies in low or nontranspiring tissues because calcium is not transported in the phloem.OrocobreAntacidCalcium formateCalcium encodingPinctada albina: Pinctada albina is a species of Pearl oyster of the genus Pinctada, known as the sharks bay shell. Another common name is the Arafura shell.Mineral trioxide aggregate: Mineral trioxide aggregate (MTA) was developed for use as a dental root repair material by Dr. Mahmoud Torabinejad, DMD, MSD, PhD Professor and Director of Advanced Specialty Education Programs in Endodontics at Loma Linda University School of Dentistry and was formulated from commercial Portland cement combined with bismuth oxide powder for radiopacity.Octacalcium phosphateAluminium hydroxide oxide: (additive)Eggshell: An eggshell is the outer covering of a hard-shelled egg and of some forms of eggs with soft outer coats. Bird eggshells contain calcium carbonate and dissolve in various acids, including the vinegar used in cooking.Phosphorus deficiency: Phosphorus deficiency is a plant disorder associated with insufficient supply of phosphorus. Phosphorus refers here to salts of phosphates (PO43−), monohydrogen phosphate (HPO42−), and dihydrogen phosphate (H2PO4−).HyperkalemiaSimulated body fluid: A simulated body fluid (SBF) is a solution with an ion concentration close to that of human blood plasma, kept under mild conditions of pH and identical physiological temperature. SBF was first introduced by Kokubo et al.Voltage-dependent calcium channel: Voltage-dependent calcium channels (VDCC) are a group of voltage-gated ion channels found in the membrane of excitable cells (e.g.White band disease: White band disease is a coral disease that affects acroporid corals and is distinguishable by the white band of dead coral tissue that it forms. The disease completely destroys the coral tissue of Caribbean acroporid corals, specifically elkhorn coral (Acropora palmata) and staghorn coral (A.EnterolithPhosphate binder: Phosphate binders are medications used to reduce the absorption of phosphate and taken with meals and snacks. They are typically used in people with chronic kidney failure (CKF) as they often have difficulty getting rid of the phosphates that get into their blood (i.Lubrication: Lubrication is the process or technique employed to reduce friction between, and wear of one or both, surfaces in proximity and moving relative to each other, by interposing a substance called a lubricant between them. The lubricant can be a solid, (e.Historadiography: Historadiography is a technique formerly utilized in the fields of histology and cellular biology to provide semiquantitative information regarding the density of a tissue sample. It is usually synonymous with microradiography.Sodium hexametaphosphateList of minerals (complete): Mineralogy is an active science in which minerals are discovered or recognised on a regular basis. Use of old mineral names is also discontinued, for example when a name is no longer considered valid.Otolith: An otolith (οτο-, oto-, ear + λιθος, lithos, a stone), also called statoconium or otoconium, is a structure in the saccule or utricle of the inner ear, specifically in the vestibular labyrinth of vertebrates. They have been identified in both extinct and extant vertebrates.Parathyroid hormone family: The parathyroid hormone family is a family of structurally and functionally related proteins. Parathyroid hormone (PTH) is a polypeptidic hormone primarily involved in calcium metabolism.Maalox: Maalox is a brand name antacid containing aluminium hydroxide and magnesium hydroxide to neutralize or reduce stomach acid.Hexagonal crystal system: In crystallography, the hexagonal crystal system is one of the 7 crystal systems, the hexagonal lattice system is one of the 7 lattice systems, and the hexagonal crystal family is one of the 6 crystal families. They are closely related and often confused with each other, but they are not the same.DihydrotachysterolIntravenous sodium bicarbonatePolyamineField emission probesFirst pass effect: The first-pass effect (also known as first-pass metabolism or presystemic metabolism) is a phenomenon of drug metabolism whereby the concentration of a drug is greatly reduced before it reaches the systemic circulation. It is the fraction of drug lost during the process of absorption which is generally related to the liver and gut wall.Calcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.Familial hypocalciuric hypercalcemiaUltra-high-molecular-weight polyethylene: Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), or high-performance polyethylene (HPPE), it has extremely long chains, with a molecular mass usually between 2 and 6 million u.Lanthanum(III) bromideDeep chlorophyll maximum: A deep chlorophyll maximum (DCM) is a subsurface maximum in the concentration of chlorophyll in the ocean or a lake. A DCM is not always present--sometimes there is more chlorophyll at the surface than at any greater depth--but it is a common feature of most aquatic ecosystems.Biocidal natural building material: A biocidal natural building material is a natural building material which has biocidal properties. The biocidal properties of biocidal natural building materials are inherent to the material, rather than being supplemented afterwards.Alkaliphile: Alkaliphiles are a class of extremophilic microbes capable of survival in alkaline (pH roughly 8.5-11) environments, growing optimally around a pH of 10.Nacre: Nacre ( also ),Definition of nacre at dictionary.com.Isotopes of calcium: Calcium (Ca) has 24 isotopes, from 34Ca to 57Ca. There are five stable isotopes (40Ca, 42Ca, 43Ca, 44Ca and 46Ca), plus one isotope (48Ca) with such a long half-life that for all practical purposes it can be considered stable.Magnesium acetateMalacoherpesviridae: Malacoherpesviridae is a family of DNA viruses in the order Herpesvirales. Molluscs serve as natural hosts.
